Normal force between ball and cone?

Click For Summary

Homework Help Overview

The discussion revolves around the normal force between a ball and a cone, focusing on the forces acting on the ball as it moves along the cone's surface. The subject area includes dynamics and forces in circular motion.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the equations of motion and the components of forces acting on the ball. There is an attempt to relate the normal force to the motion of the ball, with some questioning the absence of an angle in their calculations. Others express confusion regarding the credit received for their work and the correctness of their approach.

Discussion Status

Some participants have made progress in their understanding and calculations, while others are still seeking clarity on specific aspects of the problem. There is acknowledgment of mistakes made in earlier attempts, and one participant indicates they have resolved their confusion regarding the force components.

Contextual Notes

Participants note the absence of certain information, such as the angle and mass of the ball, which impacts their calculations. There is also mention of the need to consider the components of forces more carefully.

Homework Equations



f=ma
v^2/r

The Attempt at a Solution


∑FX= FN
∑Fy= -mg
We are not given an angle, i would have put FNcos(θ).
I have my radius as 0.25 by relation of the triangles at that point of the height being .50m
so ∑FX= FN = v^2/r = (1.2)^2/.25 = 6.25N

I forgot the mass...
 
Ok nevermind i just forgot to multiply by the mass converted to kilograms

Hi yes i marked this one solved guys i figured it out i wasn't thinking it through i needed the components. i have solved it and am now working on some impulse and momentum stuff with exploding objects
 
I'm sure i will be making another thread in T-15 minutos
